10 Claim.

This invention relates to improvements in hair waving appliances and has particular reference to a curler or the"'type imwhichamhagpin is the hair pin 9 in itsnon-clamping or normal position on the mandrel. When the members l and II are operated to adjust the hair pin ,to its activated by the operation of a curler toclaifif elampiwpn operative position with respect to a strand of hair and remain in its clamping position thereon after the curler has been removed.

An object of the invention is to provide an improved curler of the type referred to, which is of simple, practical and economical construction andwherein two hairpin-supporting members cooperate to adjust the pin from a non-clamping to a clamping position with respect to a strand of hair wound upon the mandrel of the curler.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawing which illustrates a preferred embodiment of the inventive idea.

In the drawing:-

Figure 1 is an elevation, partly in longitudinal section, of a hair curler constructed in accordance with the invention and showing the parts in position prior to the application of a hair pin to a strand of hair wound upon the curler.

Figure 2 is a view similar to Figure 1 showing the elements of the curler in operated position and with the hair pin applied to the strand.

Figure-3 is a fragmentary horizontal section through the curler taken substantially on the line 3-3 oi. Figure 5.

Figures 4 and 5 are transverse sections on the lines and 55, respectively, of Figure 1, and

Figure 6 is a similar view on the line 65 of Figure 2.

Referring more particularly to the drawing, the curler is shown as comprising a tubular mandrel I which-may be made of any light material. At one. end of the mandrel the same is providedwith opposed slots 8 forming an opening into which an end of a strand of hair may be inserted preparatory to winding said strand upon the mandrel as indicated in Figure 1.

In accordance with the present invention, means are providedfor receiving and supporting a hair pin 8, such as the well known bobby pin", on the mandrel preliminary to winding the strand of ir thereon and after this winding operation has' completed, said means are operable to adjust the hair pin 9 from a non-clamping to a clamping position relative to the strand of hair. As shown, said means comprises two co-operating members II and II each of which is substantially in the form of a collar through which the mandrel passesand both of which combine to support the strand of hairfthe member-i0, as will be seen from the following description, has imparted thereto by the member I I coordinate longitudinal and rotary movements relative to the mandrel, while the member ll has only a longitudinal movement the initial and major portion of which is made relative to the member l0. During said initial movement of the member II, the pin 9 is projected from its normal position along the mandrel and toward the strand of hair, and during this movement the member l0 operates to spread the shanks of the pin so that they will extend along the inner and outer convolutions of the curled strand- After the pin has been thus adjusted bythe longitudinal movement of the member ll relative to the member i0 and the pin has almost reached its clamping position, the member ID is engaged by the member I I and further movement of the latter to its extreme operated position also imparts a longitudinal movement to the member ID. Simultaneously, the latter member is also rotated and this rotation is designed for the purpose of releasing the hair pin 9 from the member It to permit the spread or outer shank of the hair pin to assume its normal position in which it will co-operate with its other shank to clamp the strand of hair therebetween. when this has been accomplished, the members i0 and II are restored to their normal positions and the strand of hair with the pin thereon is removed from the mandrel.

The member l0 partially embraces the mandrel I and is provided with a; beveled peripheral portion I! the purpose of which will presently appear. Said member is cut to provide an opening l3 which, in the normal position of the member, is out of alignment with the pin 9, but when said member is rotated said opening I3 is brought into. alignment with the pin so that the closed end of the latter may be projected through the member at the termination of the longitudinal movement thereof and thus permit the bight of the pin to engage the adjacent edge of the strand of hair. In order that the described rotary movement may be imparted to the member III the latter carries a pin I I which projects 'into a spiral slot l5 formed in the mandrel. when the member 10 has been actuated to the position of Figure 2 in which the opening I 3 has beenbrought into alignment with the pin 9 means are provided for restoring the member I. to its normal position of Figure 1 after pressure against the member is relieved by the operator releasing the grip upon the member II. This means is in the form of a spring i6 coiled about a rod I1 extending longitudinally of the interior of the mandrel, with one end of the spring secured to the mandrel and the other abutting against the pin H. The movement of the member l toward the strand of hair compresses said spring and when pressure against said member is relieved the spring It acts to restore said member ill to its normal position.

The member ll completely encircles the mandrel I and is provided with a pin H! the inner end of which projects into a groove is formed in the mandrel 'l and extending from a pointadjacent the left hand end of the mandrel as viewed in Figure 1 to the other. extremity thereof. By the engagement of the pin iii in said groove the member I l is permitted to slide along the mandrel but is prevented from having a rotary movement with respect thereto. 'The member Ii is provided with an enlargement 20' having a recess 2| therein adapted to receive the closed end or bight of the pin 9 when the latter is being mounted in position preparatory to its application to the strand of hair. In mounting the pin 9 on the mandrel between the members l0 and Ii, the free extremity of one of the shanks ofv the pin.9 is first inserted into the portion of the groove [9 then encircled by the member I0, and the extremity of the other shank is separated from the first extremity and rests upon the periphery of the member iii. The first or inner shank then engages in the groove is and the closed end or bight of said pin extends into the recess 2| of the member Ii. With the pin thus supported, the strand of hair is wound upon the outer end of the mandrel and when this winding operation has been completed the operator first grasps the member H and moves the same toward the member in. As said member II approaches the member ID the inner shank oi the pin travels along the groove 19 and is thus projected into the curled strand of hair. At the same time the outer shank of the pin passes over the member in and as the member ll nears said member in the spread of the outer shank increases so that its passage over the outer surface of the strand of hair will be insured. By providing the member ill with the beveled portion I! it will be obvious that the spread imparted to the shank will not be unduly increased as the member ll approaches the member in. Until the member I 1 comes into contact with the member III the latter has no movement imparted thereto, but when said engagement is. effected, and the operator continues to exert pressure against the member I i the member ill will also be moved longitudinally until the pin ll engages the outer end of the slot l5. During this movement, as previously described, the member I0 is rotated and in so doing the opening i3 is brought into alignment with the pin 9. This occurs as the member ID reaches the right hand extremity of its movement and when the opening and pin are so aligned theouter shank of said pin is permitted to restore to its normal condition in which it will cooperate with the inner shank to clamp the strand of hair therebetween. At this time the closed end ber I0 is thus relieved the spring I6 will restore said member to its normal position. The strand of hair with the pin clamped thereon may now be removed from the mandrel by an outward pressure against the closed end of the pin toward the free end of the mandrel.
